[13-Cis-retinoic acid: a new form of treatment of rosacea (author's transl)].

13-cis-retinoic acid was given with good results to 7 patients with exceptionally severe rosacea. Side effects were transitory and of minor consequence and subsided quickly on reduction of the dosage and topical application of mild cosmetics. The long-lasting remissions recorded to date indicate that 13-cis-retinoic acid may prove a new and successful approach to the treatment of rosacea.
